or clamped firmly. If hammerdrilling thin material, use a wood “back-up” block to prevent damage 
to the material.
Press mode selector button and turn the mode selector (F) to the drill bit symbol for hammerdrilling, 
to the hammer symbol for hammering or to the hammerdrill symbol for hammerdrilling. 

HAMMERDRILL OPERATION
 1. When hammerdrilling, use just enough force on the hammer to keep it from bouncing 

excessively or “rising” off the bit. Too much force will cause slower hammerdrilling speeds, 
overheating, and a lower hammerdrilling rate.

  2.  Drill straight, keeping the bit at a right angle to the work. Do not exert side pressure on the bit 

when hammerdrilling as this will cause clogging of the bit flutes and a slower hammerdrilling 
speed.

  3. When hammerdrilling deep holes, if the hammer speed starts to drop off, pull the bit partially 

out of the hole with the tool still running to help clear debris from the hole.

  4. For masonry, use carbide-tipped bits or masonry bits. A smooth even flow of dust indicates 

the proper hammerdrilling rate.

Your tool was properly lubricated before leaving the factory. In from two to six months, depending 
upon use, take or send your tool to an authorized service center for a complete cleaning, 
inspection and lubrication. Tools used constantly on production jobs will need relubrication more 
often. Also, tools “out of service” for long periods should be relubricated before being put back 
to work.
